Coding apparatus for recoding coded bit streams |
摘要 |
A code amount of each block of primary-coded bit streams and a degree of complexity of image using quantization coefficients, i.e., a degree of difficulty in coding are calculated(S15). Then, recoding is performed by setting a target code amount every block based on the degree of difficulty in coding, and thus secondary-coded bit streams with uniform picture quality can be generated while suppressing the influence of code amount control of the primary-coded bit streams. <IMAGE> |
